.. To all ,whom t may concern VYBeY it known that I, VICTOR JENNINGS, acitizen of the United States, residing at .lVorcester, in the county of Worcester, State of lVIassachusetts, have invented ra certain new and useful Improvement in Woven TubesL and Methods of Weaving the Same, of `which the following is. a specification,

v. reference being had therein to the accomioA panying drawings.' The invention consists in a tubular woven fabric having `a plurality of sides meeting at angles, the corners being langularly de-V fined inthe weaving. Also,in aitubular woven fabric having an opening extending transverselyacross manifold warp-spaces as f well as longitudinally of the warps, with its 'lateral margins formed with Lselvages pro'- iy 'f duced inthe weaving; 'Also,in a tube woven with an Vopening as"aforesaid inone side thereof and witha narrow longitudinalslit in another side, and adapted to constitute ablank ffor a lvehicle-lamp cover. a novel vmethod of weaving.

Thev features-of the invention are illustrated inthe drawings, inwhich latter* Also in .'Figure,1":isan isometric view of a woven leo v'tube.embodyingfthe said features.

The top and bottom plies a and 6in said figures correspondto the sides l and 2 of s' Fig. l, and in the web Vor fabric asV woven in a loomr the said plies are extended transverselyand iat to thefull width of the said sides. rllhetwonarrow intermediate plies cpd, at the right in Figs .3 and 4 constitute t l itself.

In weaving a plain tube,.as in thelower,

portion ofthe tubularvfabric'or article of.

Figi below thev opening orwindow and slit,v f4?, the threads are interwovenfsubstantially as in Fig. 3. In the latter a singlev weft-thread ZL is'einployed. Starting at the left Vin Fig. 3, the first lpick-of the weftthread it extends from the extreme left` to the extremefright through the top ply a.

The second pick extends from the extreme right through the upperA right-handY vinter-V mediate ply 0 to the transverselyintermediate point C. The third pick extends from point c from `left to right through the lower right-hand intermediate ply dto the extreme The fourth pick extends through the bottom ply b from the Vextre'i'ne right to the extreme left. The fifth pick extends from left to right through thel lower intermediate ply to the transversely-intermediate point f@ rlhe sixthpick .extends from right to left throughthe'upper left-hand intermediate ply e. to the extreme left. The seventh pick extends from the extreme left to the extreme right throu'gha secondv shed in the top ply a, and in like manner the eighth, ninth, tenth, eleventh, andV twelfth picks extend in thesame directions respec tively as the second to sixth picks, through theremainingsuccessive plies, but through a second shed in every suchply. One round or repeat of the weave is completed by the return of the weft to the starting side in Fig. 3, after completing the pick from right to leftthrough the left-hand upper intermediate ply e. In consequence of the outer portions of the right-'hand lintermediate.y

plies c, d, being joined in the weaving tothe:

each other by causing the weft in the case of each thereof to pass inwardly within the Vsecond pick vextends from right to leftV right hand portions of the top and bottom plies a, b, and in consequence of the inner portions of such intermediate plies being joined together inl the weaving, the said plies c, d, will together constitute one side of the tube of Fig. 1 when straightened out in line transversely with each other by moving the sides that are constituted by the top and bottom plies a, b, apart from each other. The fourth side of the tube will be constituted bythe left-hand intermediate lplies e, f, when similarly straightened out in line transversely with each other. The result vof weaving the web in superimposed plies united by the weft-threads along the lines of junction of the plies a, b, with the plies 0, d, and e, f, is that folds or bends and creases are produced in the' web, serving to Vdefine Vthe corners of the tube, which retain normally an angular set. Y .y

The opening or window 3a is produced, as shown at the right in Figs. 4 and 5, by floating the warp-threads g', g', etc., of the inner portions of the two intermediate plies 0, d, which make one'folded-in side of the tube, and interweaving the weft with only the warp-threads of the outer portions of such intermediate plies. rihe narrow woven portions c2, d2, thus Vproduced are formedl with selvages', and are left unconnected with same and also return outwardly therein without crossing over to the other thereof.` The'narrow slit 4a is produced by forming the inner portions of the intermediate plies f, which together constitute the side containing such slit, with distinct edges, unconnected with each other throughout the length of the slit. 'The selvages at such slit are produced by causing the weft of each such ply to extend inwardly through the ply and then return outwardly without crossing Vover to the other ply.

Fig. 4 represents one manner in which the portion of the tube containing the opening or window and slit may bwoven with the aid Vof two shuttles. Thus, in the case of one weft-thread, 71,', the first pick thereof, starting at the extreme left, extends to the extreme right through the top ply a; the

Vthrough the narrow intermediate portion 02,' the third pick returns from left to right through vsuch portion; the fourth pick extends yfrom extreme right to extreme yleft through the top ply a; the fifth pick extends from left to right through intermediate ply e; and the sixth pick extends from right to left through said intermediate ply e back to the starting point. The other weftthread,.

p' h2, starting at the extreme left, extends from left to the extreme right throughply I); the

second pick' extends" from right to leftV through thefnarrow portion d2; the' third point. Y Fig. 5 illustrates the method of weaving,

ply t; the fifth pick extends from left to right through lower intermediate ply f to the inner edge of the` latter; and the sixth pick extends from right to left through said lower intermediate ply f back to the starting and substantially the Vfabric structure, in

c ase the narrow slit 4 is omitted.VA `Starting at the extreme left, the first pick of weft lex! tends through ply a to the extreme right; the second pick of'iweft extends from right to left through the narrow portionczfthe third pick returns from left to right through the said narrow portion 02,1 the fourth pick returns from extreme right to extreme left through ply a; the fifth pick extends from extreme left toward the right through upper intermediate ply e; thesixth pick extends from right to left through lower intermediate ply f; the seventh pick extends from extreme left to extreme right through ply b the eighth pick extends from right to leftv through narrow intermediate portion d'the ninth pick extendsk from left to 'right -v through'said portion: d2; the tenth pick exfrtends from extreme rightto extreme' left' Vthrough ply b; Vthe eleventh piekV extends from left to right through lower interme-V 'i diate ply f; and the twelfth piek extends from right to left through upper intermediate ply e back to the starting point. When the opening or window a3 has been given the desired measurement in thedirectionrofi.the length'of the tube, theweft is interwoven again, as in Fig.v 3, with the warp-threadswhich have been fioated in producing V.the

said opening or window; Thereby solid orr continuous fabric will be producedcontiguous tothe opening or window. `Above the level of the top of the opening'or window, the slit 4a is continued by a method of weaving similar to that illustrated 'in' Fig. 5 in connection with the opening or window.

los

The weaving of the tube is continued byYV Y' repetition of the piain tubular portion, followed by portions containing an opening or window and slit, and so on.

rIhe blank produced in manner vherein Vde scribed and shown in Fig. 1 is more-particularly adaptedto be utilized in the vproduction of a cover for a vehicle-lamp. The up-v per and lower ends ofthe said blank will be j i cut, shaped,y and stitched or lotherwise treated tozform a top or hood and bottom,

the light of the lamp to issue for purposes of illumination in the required direction. The floating or loose warp-threads crossing the said opening or'window will be trimmed ofi'.

Suitable fastenings will be provided for securing the cover in closed condition about the lamp. The width of slitla may be inand with each of said sides composed of its individual set of warp threads.

2. A tubular woven fabric having woven in one side of the tube an opening or window extending transversely across manifold warp-spaces as well Vas, longitudinally of the warps, with its lateral margins formed with selvages produced in the weaving, the intervening warp-threads floated from top to bottom of the opening or window, 'and weftthreads omitted from said topto said bottom.

3. A tubular woven fabric having in one side thereof an opening or window extendingk transversely across manifold warpspaces as well as longitudinally of the warps', with its lateral margins formed with selvages produced in the weaving, and with Va longitudinal selvaged slit in another side thereof.

4. A tubular woven fabric having a plurality of sides .greater than two meeting at angles, the corners defined in the weaving,

and having woven in one ofthe said sides an Y opening or window extending vtransversely across manifold warp-spaces as Well as. longitudinally of the Awarps, with its lateral margins formed with selvages produced in the weaving.

5. A tubularwoven fabric'having a plurality of sides meeting at angles, vthe corners defined in the weaving, "and having wovenin one of the said sides an opening or 'window extending transversely across manifold warp-spaces as well as longitudinally of the warps, and also having woven in another-of the said sides a narrow longitudinal slit,

copies of this patent may be obtained for said opening or window and said slit having lateral margins formed with selvages produced in the weaving.`

6. Themethod of producing a rectangular woven tube with the corners thereof defined in the weaving, which consists in weaving two opposite sides thereof in flat extended planes, one above the other, and weaving two connecting sides in folded-in state opposite each other between said flat extended plies, with the outer portions of each folded side joined in the weaving to the contiguous margins of said plies.

7, The method of weaving which consists in weaving two plies of cloth, one above the other, weaving a connecting portion as aV fiat inward foldV between the said plies, with the outer margins of the folded connecting portion joined in the weaving to the contiguous margins of the said plies, and producing an opening or window in the said connecting portion by iioating the warps of the latter at and adjacent the bend or bight thereof, forming selvages on the lateral margins of the opening or window by returning the weft upon itself within the same plane of the fold after each pick to the'inner margin thereof.

` 8. The method' of producing a rectangular woventube vhaving the corners 'at its anglesV defined in the weaving, and of forming an opening or window in aside of said tube,

i which consists in weaving opposite sides in flat extended plies, one above the other,

weaving eachv connecting side' as a flat inward fold between such extended plies, with YVthe outer portions of the '1n-folded side joined in the weaving to the contiguous mar- .Lplane of'saidfold after each pick to the in- Vner Vmargin thereof.

In testimony whereof I aflix my signature in presence of two witnesses.
